3. Nitrogen flows from a large tank, through a convergent nozzle of 2 in. tip diameter, into the atmosphere. The temperature in the tank is 200 F. Calculate pressure, velocity, temperature, and sonic velocity at the exit, and calculate the flow rate when the tank pressure is (a) 30 psia and (b) 25 psia. Barometric pressure is 15.0 psia. What is the lowest tank pressure that will produce sonic velocity in the jet

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
